容积式液压缸带压精密测定液压部件微泄漏量

Measuring Micro-leakage Precisely of Hydraulic Productions with the Volumetric Cylinder Under Certain Pressure

带压精密测定液压零部件产品微小泄漏量,一直是困扰液压产品生产行业的难题。本文阐述了用容积式液压缸精密测定液压部件产品微泄漏的原理及采取的主要技术措施。

Measuring precisely micro-leakage of hydraulic productions under certain pressure is always a diffi- cult problem for the factories that produce hydraulic components.This paper elaborated the principle and tech- nical steps measuring micro-leakage precisely of hydraulic productions with the volumetric cylinder under cer- tain pressure.
